Notes: These are representative of a new generation of rifle grenades known
broadly as BTU (Bullet Trap Universal) grenades. Smoke grenades come in white,
black, or colored smoke. The ILLUM grenade uses the basic WP body, but fires a
60000-candlepower parachute flare. The rocket-assisted grenade is designed for
more punch and to allow longer-range shots. They require no special adapters and
can be fired using regular service ammunition.
